Personally it is the no longer produced ProKennex super wrap ovegrip. I tried Wilson Pro, Yonex, Gamma, Tourna, and so on and none could stack up against it. I will have to settle when I run out of the ones I have left.

Original Tourna Grip is the only one I use anymore. The Tourna II isn't that bad but I like the original better. Never tried the Wilson Pro, but I don't like the Yonex Supergrap as it slips in my hand once it gets sweaty. The Yonex is very comfortable though.

Yonex SuperGrap and Wilson Pro Overgrip are very similar. I prefer Wilson Pro for it's feel, and that it's colors don't rub off on your hand or the handle, like SuperGrap does. That's my biggest problem with it, my hands and a white replacement grip turned green.

I felt a Pointfore grip and I actually really liked it. It was new. I've never seem them in stores though.

Babolat Original VS is too dry of a grip. It's OK for the first hit, then it seems like it absorbs the dirt and dust and gets real bad, and fast. Babolat Pro Team was better.

I prefer tacky grips- like Wilson Pro and TournaGrip Original and II.

I tried one Pacific overgrip and it was REALLY tacky. It was good, but perhaps too tacky- like it could easily give a lot of people blisters.
Fischer makes a very good, very durable, tacky almost rubbery feeling, overgrip.

Kirschbaum Blue is a good overgrip. It has slight bevels that someone may or may not like.

BTW Rulo, I hear a lot of people like TournaGrip over leather. I use Wilson Pro ovef a Pacific leather grip- it's a pretty good combo.

The best overgrip is by far the Prince DuraTac. They last forever and are very tacky yet soft at the same time. The wilson pro is just made to be used only once by the pros since they are sponsored and get them for free. They don't seem to last beacuse when I compare it to the first day with the third day, they are totally different from each other! Not a good thing!

idk i tried wilson pro and it didnt work for me at all. they felt great at first, but after awhile it began to lose its feel. in overgrips i like head xtreme soft but i just stick with replacement grip prince contour

I'm incredibly fussy when it comes to overgrips (usually lose too much feel) and the only one I'll bother with is Volkl Super Grip II.

Good tack, but not so much your hand feels glued down. Very long lasting, good sweat absorption and an excellent feel. Only down-side, for some, is that, while it isn't super thick, it isn't micro thin.
